PITSTOP can deobfuscate base64 encoded and AES encrypted commands.3
PITSTOP can listen and evaluate incoming commands on the domain socket, created by PITHOOK malware, located at /data/runtime/cockpit/wd.fd for a predefined magic byte sequence. PITSTOP can then duplicate the socket for further communication over TLS.4
PITSTOP can listen over the Unix domain socket located at /data/runtime/cockpit/wd.fd.5
Standing S1123
Reach is how much of ATT&CK this tool touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
Reach
Techniques5Bottom 23%
23rd percentile · 77% of 825 ATT&CK software entries have more Enterprise techniques.
Tactics432nd pct
32nd percentile · 68% of 825 ATT&CK software entries have more tactics spanned.
Threat groups061% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
Campaign185% tie · 8 values
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
